Health supplements are not medicines and can never replace them. Many patients have such fears that the treatment of diabetes is either to take western medicine or insulin injection, eating more and more will have side effects, therefore, the doctor prescribed drugs to reduce the amount of taking or do not eat, but privately to buy some health care products to replace the drug treatment. This practice is extremely wrong, because health care products can not lower sugar, at most can play some auxiliary role, if only eat health care products, do not control the diet, do not follow medical advice to take drugs, blood sugar will not be controlled, will have adverse effects on the whole body organs, and even cause complications, delay the disease.
